2- Claims.

Y This invention appertains to a novel and use-- ful process andapparatus for disposing of garbage.

An object of this invention is to conduct refuse and liquid to anoxidation zone, oxidize the refuse while in the said zone and separatethe liquid from the refuse and exhaust the gases while oxidizing therefuse.

Another object of this invention is to conduct liquid and refuse to aseparator, which extracts the liquid from the refuse, then to spread orseparate the refuse prior to oxidation thereof, then mix the resultingashes and previously separated liquid for subsequent disposal in aconventional sewer line.

Ancillary objects and features of novelty will become apparent to thoseskilled in the art, in following the description of thepreferred form ofthe invention, illustrated in the accompanying drawings, wherein:

I Figure l is a partially schematic and partially sectional view of thepreferred form of the inven tion;

Figure 2 is a sectional view taken substantially on the line 2--2 ofFigure 1 and in the direction of the arrows;

Figure 3 is a sectional view taken on the line 33 of Figure 1 and in thedirection of the arrows, and;

Figure 4 is a sectional view taken on the line 44 of Figure 1.

This invention has been developed to provide a device for moreefiicaciously disposing of garbage or other refuse and simultaneouslyutilizing the heat of combustion in the disposal process for warming orheating liquid in a storage tank for various and sundry uses.

The preferred process for performing the heating of water and disposingof refuse is as follows:

Various types of refuse and liquid are conducted through a tube in, thenthey enter a housing 14 having a sleeve l2 therearound. The said housingI4 is supplied with a roller-type separator t6 consisting of a pluralityof spaced rollers l8 journalled in the said housing l4. By this meansthe refuse and liquid is separated, the liquid falling from the housing14 through the space between the rollers IS. The refuse is of courseconducted over the rollers due to the force or pull of gravity.

A gate valve 2!] is attached to a suitable collar 22, which is in turnsecured to the said housing M. The refuse travels across the separatorI6 and through the gate valve 20, the refuse urging the valve to theopen position to permit the other liquid issuing from the T fitting. 3t.

2 entry of the refuse into a firebox generally indicated at 24.

The refuse impinges upon a substantially T-shaped fitting 26 whichextends through a grate 28. The said T fitting 26 has a plurality ofarms or fingers 30 extending therefrom which are in reality b-afiles forspreading the refuse.

The said grate 28 is Of a special configuration, as is readily apparentfrom correlation of Figures 1 and 3. The said grate has asubstantiallyarouate bottom with side walls 32 at the end thereof.

The liquid which has been deposited in the said sleeve 52 is conducteddue to gravity through a conduit 34' which connects with a T fitting 36.The said T fitting has a closure 38 at one end thereof for use incleansing purposes and the opposite end thereof is open and in communication with an ash pit 42. The said ash pit is at the bottom of the firebox 24 and is of course, beneath the said grate 28.

A gas manifold 44 extends through the said ash pit 42 and has aplurality of jets 46 extending therefrom.. Any number of manifolds 44may be supplied (see Figure 3) and of course, any suit- .able number ofgas jets 46 maybe utilized in association therewith. Due to theconfiguration of the said grate 28, the fiame from the jets 46 may bedirected so as to impinge upon a relatively large area thereof for largeo high efficiency in heating and burning.

Of course, means for supplying gas to the manifold 44 is suppliedhowever, the particular means is immaterial to the process. By the gasburning devices described herein, the refuse is burned and the ashessettle or fall through the ash pit 42. However, while the ashes are inthe ash pit they come in direct communication with the water or Aconventional sewageline 43 also extends within vthe ash pit 42 in orderto receive fluid and ashes for subsequent disposal. While the refuse isbeing oxidized in the oxidation zone or fire box 24, certain of the heattherein is obviously excess heat. Therefore, a coil 50 is supplied inthe said fire box 24 or oxidation zone having an inlet line 52 and anoutlet line 56 extending therefrom. The said inlet line terminates inthe lower portion of a conventional storage tank 58 while the saidoutlet line terminates adjacent the upper portion of the said tank 58.Of course, as the liquid, preferably water is introduced into the coil5&3 through the inlet line 52, it is heated and is constantly rising tothe upper portion of the said tank 58.

A further consideration in the process is the exhausting of noxiousgases. To this end a plurality of apertures 60 and62 respectively aresupplied in the said housing I4 for communicating the said housing withthe bore of the said sleeve I2. Gases from the refuse will extendthrough these apertures through a conduit or pipe 66 which in turnterminates in a main flue 68. The said main flue also is incommunication with the fire box' 24 or oxidation zone for conductingflue gases therefrom. The structure of the furnace generally indicatedat 16 defines various elements such as the oxidation zone.

A flap valve 18 is pivotally secured, to .the:ter.- minal portion of thesaid conduit I9 which is normally closed by gravity for the obviouspurposes of preventing gases from issuing through the said pipe orconduit ill in the undesired direction. Further, a clean out plug 80 maybe supplied in the said sleeve I2 for the obvious purpose of lendingaccess ,to the interior of the sleeve and also the interior of the saidhousing I4.

Thestructural features of the invention as well as portions of theprocess or method will be set forth more indetail at. this .time. Aconventional sink seen at 82 is illustrated as being conventionallymounted. The usual outlet pipe 84 is associated therewith andcommunicates with the said tube or conduit Ill. This construction isoptional, since it is obvious thatthe conventional drain pipe 84 maybeconnected or operatively associated with the usual drain in an existingstructure. Further, for convenience a faucet 86 may be positionedadjacent the ingress portion of the said conduit Ill and also, a belltrap 88 may be supplied in the said conduit H].

The said furnace indicated generally at 16' is preferably composed of aninner housing 90 made of any suitable material having a furthersubstantially rectangular smaller housing 92 secured therein. Arelatively large aperture 94 is provided in the base of the said housing92 and the upper portion of said housing 92 is completely open. The saidgrate 28 is positioned immediately beneath the said aperture 94.v

The exterior of the said furnace is preferably an additional case 98 ofany suitable material which is spaced from the said housing 99, thusproviding an insulating air space- Of course, suitable apertures areprovided in the case 98 and the housing 90 in order to accommodate thesleeve I2 and the said housing I4. Further, the said pipe or conduit 34is preferably positioned in the aforementioned air space, while theclean out plug BI] is positioned exteriorly of the outermost case 98.

In order. to supply proper ventilation within the oxidation zone, thesubstantially T-shaped element 25 extends beneath the grate 28 andterminates above it.

It will be noted that the said air space has communicated therewith asubstantially elbow shaped connector I which extends through the outercase 98 and is in direct communication with the main flue '68.Obviously, this elbow connection IE0 is for the purpose of conductingundesired gases therefrom. There is also supplied a pipe I02 having adetachable cap :04 thereon which extends through the housing 90 and alsothrough the outer case 98. This pipe I92 is adapted to receive certaintypes of refuse such as vacuum cleaner spillings and the like.

A vent stack )8 extends from the said water tank 58 for use inassociation with certain types of water storage systems. In the eventthat the installation of the present invention is a con- 4 I version jobin an existing structure and an automatic heater is utilized inconnection with this portion of the invention, the stack I08 may becapped because it is not necessary. Various pipes extend from thesystem, the said pipe Ill] indicating the heated water outlet pipe, andthe pipe H2 indicating the cold water inlet and the pipe H4 indicatingthe gas service or supply pipe. A conventional manually operated valve II6 may be supplied in the said pipe I I4 and beyond the said valve H6 isa conventional adjustable thermostatically operative valve generallyindicated at H8. Ofcourse, the usual rod or thermostatic bar I20 extendstherefrom and terminates in the tank 58.

When heated water is required in the tank 58, gas flows to the burnersby the automatic operation of the thermostatically controlled valve IIB.A pilot light is maintained in the heating zone or oxidation zone bymeans of a small conductor I22 which is connected with the safety valvegenerally indicated at I24 and which safety valve is in turn associatedwith the inlet gas line H4. Through this expedient the burners areignited. The water in the tank 58 is heated to the. required temperaturethrough the utility of the coil 50 described above.

A thermostat rod I23 extends from the safety valve I24 and terminates inthe oxidation zone adjacent the pilot light tube I22 terminal. This rodI23 actuates the valve I24 in a conventional manner and a manual valveI25 is associated with the safety valve I24 to serve its usual function.

The main gas burner is positioned as described and while the gas burneris in operation heating the water, the garbage or other refuse in theoxidation zone is dried out and burned to ashes. When the water reachesthe required temperature, the gas is automatically turned off by thethermostatically controlled valve I I 8. Of course, during the time thegas is not delivered to the jet 4B, the heat retained in the oxidationchamber continues to dry out the refuse in the oven or that refuse whichmay enter the oven during that period of time.

Of course, by setting the thermostat in the thermostatically controlledvalve by the utility of the conventional means such as a handle, theentire unit may be thoroughly steamed and cleaned by opening the faucet88 and permitting water to enter at the disposal inlet.

While there has been described and illustrated but the preferentialforms of the invention, it is apparent that variations may be madewithout departing from the spirit thereof. Accordingly, limitation issought only in accordance with the scope of the following claims.
